A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.


The end (or ends) of the lamp that fits into the socket.
Medium (E26)

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".

Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Brightness (Lumens)

A rating of the inital light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.

Bulb Technology

The technology implemented by the bulb, e.g. incandescent, halogen, LED

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
Average Rated Life (hr)

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Length (in)

Diameter (in)

Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
Diameter (in)

Contains Mercury (Hg)

Contains some level of the element Mercury. Typically, bulbs containing Mercury display the symbol 'Hg'.

    Comments about Overdrive 15 Watt, R30 Warm White Compact Fluorescent Medium Base Bulb:

    These bulbs are less than 1/2 the price of the next least expensive bulb of this type. I have only had to use 4 of them so far but the seem to be doing well. We use them in the ceiling of our Olive Oil and Balsamic Vinegar store to shine on our displays of Stainless steel containers that we serve our products out of. The original bulbs were incandescent spots that are in a canister on track lighting, those burned out after only 2 months of use because of the heat. We are eventually going to go to LCD lighting but we are talking close to $1500 to do this. As such we are trying out these lights until more cash becomes available.
